Help me with this ASAP for brainliest

hope it helps

Step-by-step explanation:

x.f. = fx

0.5* 5=. 2.5

1.5* 28 = 37.5

2.5*32 =80

3.5*26=91

4.5*9=40.5

total fx = 251.5

mean = total fx/ N

= 251.5/100

= 2.515

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌
